Winch position control method and device, computer equipment and storage medium

By controlling the operation of the winch drum based on a preset height value during the drilling platform's descent and tripping operations, and combining this with the height deviation value obtained by the identification and positioning device, precise alignment of the chuck and drill pipe joint is achieved. This solves the problem of inaccurate chuck alignment in existing technologies and improves operational efficiency and automation level.

AI Technical Summary

Technical Problem

In existing technologies, the alignment between the chuck and the drill pipe joint is inaccurate and non-standard drill pipes cannot be automatically processed, leading to interruptions in automated operations and reduced efficiency.

Method used

By controlling the operation of the winch drum based on a preset height value during the drilling platform's descent and tripping operations, detecting whether the chuck has reached the boundary of the preset area, obtaining the height deviation value, and using an identification and positioning device to obtain feature information, closed-loop feedback control is achieved until the chuck is aligned with the drill pipe joint.

Benefits of technology

It achieves precise alignment between the jack and the drill pipe joint, improves work efficiency, ensures the level of automation, and dynamically compensates for positioning errors caused by factors such as inconsistent drill pipe length and cable elongation.

Abstract

The invention relates to the technical field of petroleum equipment, and discloses a winch position control method and device, computer equipment and a storage medium, and the method comprises the steps that in the drilling working condition of a drilling platform, operation of a winch roller is controlled based on a first preset height value between an elevator and a wellhead position, and the winch roller controls the elevator to vertically move upwards by winding a steel cable; whether an elevator reaches the lower boundary of a first preset area or not in the operation process of the winch roller is detected, and the first preset area is the area containing the upper end connector of the drill rod three-joint unit; when the elevator reaches the lower boundary of the first preset area, a first height deviation value between the elevator and the upper end connector of the drill rod three-joint unit is obtained; and according to the first height deviation value, a winch roller is controlled to operate until the elevator and the upper end connector of the drill rod three-joint unit are in an aligned state. The problems that in the prior art, alignment of an elevator and a drill rod connector is not accurate, and a non-standard drill rod cannot be automatically processed are solved.
